Dosing Volume

GEA Procomac has developed the new Aseptic Dual Filling

System for the bottling of still beverages, that contain pulps,

fibres, and pieces of fruit or cereals with dimensions up to

10 x 10 x 10 mm. This is believed to be the first time this process has

been used in a cold-fill environment for PET bottles. The Piston Doser

PX achieves the aseptic dosing of the valuable solid pieces ahead of

the subsequent liquid filling process, with a high level of accuracy.

The Piston Doser PX is simple but effective. A cam-driven piston first

Aseptic cold dosing for fruits and cereals

GEA Process Engineeringengineering for a better world

draws into a cylinder the prescribed volume of solid particles, before

injecting it into the awaiting PET bottle. The bottle then moves onto

a standard volumetric, electronic filler, the Fillstar FX, to add the

liquid juice and complete the aseptic filling process. The dual fill

system requires a 2 stream process line: one dedicated to the thermal

treatment of the pieces and the other to the thermal treatment of the

clear liquid.

The Piston Doser PX

Features Benefits

Aseptic design Suitable for HA and LA applications.

Allows the dosing of cold solid particles in aseptic conditions.

Automatic dosing adjustment

Accurate dosing to prevent wastage of high value product.Very reliable. Easily adjusted by linear motors.

No contact between filling nozzle and bottle neck

Mandatory for Low Acid aseptic beverages.

Simple design Low maintenance.

Volumetric measurement No need for weighing equipment or flow meters.

High Speed dosing Designed to match production volumes of Fillstar FX – up to 800 bpm.

Built-in CIP/SIP and sterile water rinsing

Fully automatic cleaning and sterilization cycle and fast product change over availability.

Compact Small footprint.

Gentle filling Negligible damage rate in the final beverage.

Aseptic integrity

The aseptic integrity of the Piston Doser is maintained with the inclusion of a

hygienic seal around the piston which prevents product leaking through to the

non-aseptic side. Dosing volume can easily be regulated from 30 to 150 ml by

changing the dosing value on the HMI. The stroke of the piston is automatically

adjusted by a linear motor. This provides adequate dosing for most products in

PET bottles of up to 2 litres. Smaller/Greater dosing volumes may be achieved

simply by changing the diameter of the cylinder.

The Piston Doser PX is ideal for adding large pieces of pulp, fibre, fruit or cereal

to still beverages, both High Acid and Low Acid, or for filling product whose

density does not allow the consistent distribution of the pieces.
